Sanding is the least rewarding and most decisive part of a build — it is only under paint that you find out whether you rushed it. This section brings together everything that removes and levels material: sanding sponges that follow a curve, hard sticks that hold a true plane, files for faster stock removal, and abrasive papers across the whole grit ladder, from a coarse first pass down to polishing. Which of the four you want is decided less by the material than by the shape of the surface under it, so the four categories are deliberately kept apart.

Three things. The sprue stub left on a separated part, the mould seam that runs the length of a fuselage or a barrel, and a filled joint. Each wants a different approach: a stub only needs trimming and a pass with a fine grit, a mould seam has to be taken down evenly along its whole length, and filler is worked from a coarser grit towards a fine one until the transition disappears.
The number states coarseness: low values cut fast and leave deep scratches, high values work slowly and refine the surface. The rule is simply not to skip grades. Jump from a coarse grit straight to a very fine one and the deep scratches never go away — they reappear under the gloss coat. Move one step at a time and check the surface in raking light.
On a flat panel the abrasive has to hold a plane, or the surface ripples, which is the job of sanding sticks with a hard core. On a curve you want the opposite, because a rigid tool shaves the highest point off; that is where sanding sponges belong. Into a narrow groove and along an edge, a thin file does the work.
Styrene sands easily and clogs the abrasive quickly. Resin is harder and dustier, and its dust is a health hazard, so sand it wet or with extraction. Cured cyanoacrylate and two-part putty are harder than their surroundings, so work them gently or the plastic around the repair goes down faster than the repair itself.
A model sanded smooth and blown free of dust is ready for painting, where the quality of the preparation shows up before anything else.
